Things to Do in Oita in 2026: The Onsen Prefecture

Oita is Japan’s Onsen Prefecture, and that single fact shapes everything: it produces more hot-spring water than anywhere else in the country, and its sights radiate out from that geothermal heat — the steaming “hells” of Beppu, the cure-springs of the highlands, the art village under Mt. Yufu. But the prefecture has more than baths. On its remote north-eastern peninsula a thousand-year-old mountain Buddhism left giant Buddhas carved into cliffs, and on its coast sit two of Kyushu’s most perfectly preserved old towns. This guide rounds up the experiences worth building a trip around, grouped by area, so you can see how the pieces fit.

At a glance

• Signature foods: toriten (chicken tempura), Bungo beef, seki-aji and seki-saba
• Time needed: 2 days for one area, 4-5 to combine onsen and culture

See the steam: Beppu’s hells and baths

The defining Oita experience is Beppu, where the earth’s heat is so close to the surface that whole hillsides exhale steam. Start with the jigoku (“hells”) — vivid volcanic pools kept as spectacles rather than baths: the cobalt-blue Umi Jigoku, the blood-red Chinoike Jigoku, the bubbling Kamado Jigoku. A combined two-day “Hell Tour” ticket (about ¥2,200 adult, approx. 2026) covers them. Then put yourself in the water: be buried to the neck in naturally heated sand at the historic Takegawara Onsen, soak in the milky sulfur baths of Myoban, and cook your own lunch over a geothermal vent at the Jigoku Mushi Kobo steam kitchen in Kannawa. It is vivid, participatory and the clearest first taste of the prefecture. Our Beppu onsen-capital itinerary sequences all of it across two days.

Slow down: Yufuin’s onsen, art and craft

Half an hour over the hills, Yufuin is the sophisticated face of an onsen town. Walk the Yunotsubo lane down to Lake Kinrin, which releases a famous low mist on cold mornings, all under the twin peaks of Mt. Yufu. The cultural anchor is the COMICO Art Museum, a small, serious contemporary collection (Murakami, Nara, Sugimoto) in a striking charred-timber building, shown by timed reservation. Add the reassembled craft houses of the Folk Art Village and a hillside soba lunch, and stay, if you can, at one of the celebrated villa ryokan. Yufuin is the place for couples and for a splurge; our Yufuin onsen guide covers it in full.

Take the waters: Nagayu’s carbonated cure

In the hills of Taketa, Nagayu Onsen holds Japan’s richest concentration of naturally carbonated springs — water so charged with CO2 that bubbles bead on your skin as you soak, and which is drunk as well as bathed in. The signature bath is the striped Lamune Onsen-kan, designed by the artist-architect Terunobu Fujimori, where the carbonated pool is kept deliberately tepid so the fizz stays in the water. It is the heart of a genuine cure-town tradition, paired with the volcanic moorland of the Kuju highlands above — the Tadewara marsh boardwalk and Japan’s tallest pedestrian suspension bridge at Kokonoe. This is the wellness side of Oita, set out in our Nagayu wellness onsen guide.

Go deep: the sacred Kunisaki Peninsula

For a second or third trip to Japan, the round volcanic Kunisaki Peninsula in the far north-east is the most rewarding part of Oita. From the 8th century a syncretic mountain faith called Rokugo Manzan grew across its valleys, leaving an extraordinary sacred landscape: Usa Jingu, head shrine of all 40,000 Hachiman shrines; Fuki-ji, whose Odo hall is the oldest wooden building in Kyushu; the Heian statuary of Maki Odo; and the Kumano Magaibutsu, giant Buddhas carved straight into a cliff and reached by a famously rough stone staircase. Nearby, Bungo-Takada’s Showa-no-Machi revives a 1950s shopping street as a living museum of mid-century nostalgia. Remote, deeply old and unlike anywhere else.

Walk old Japan: the castle towns and stone Buddhas

Two of Kyushu’s most atmospheric old towns sit on Oita’s coast and draw almost no foreign visitors. Kitsuki is a unique “sandwich” castle town — samurai quarters on two facing hills above a merchant valley, with cobbled stone slopes you can walk in a rented kimono. Down the coast, Usuki guards Japan’s only stone Buddhas designated National Treasures: more than sixty Heian and Kamakura faces carved into cliffs, backed by an Edo old town of temple lanes and soy-sauce houses where fugu is the winter speciality. They make a quiet, walkable pairing for travellers who have already seen the headline onsen towns; our Kitsuki and Usuki itinerary links them with a coastal night between.

Eat: toriten, Bungo beef and the famous mackerel

Oita’s table is distinctive. The signature dish is toriten — lightly battered chicken tempura with a tart citrus-soy dip — eaten across the prefecture far more than fried chicken. Bungo beef is the local wagyu, and the prefecture is proud of its seafood, above all seki-aji and seki-saba, prized horse mackerel and mackerel landed in the fierce tides off Saganoseki (seki-aji is at its best roughly July to September, seki-saba December to March). In Beppu, eat the steamed seafood and vegetables cooked in geothermal “hell steam”; in Usuki, try fugu in winter. None of it is fussy, and all of it is worth seeking out.

How long do you need?

Two days is enough for any single area — Beppu, or Yufuin, or the carbonated springs, or the peninsula. To combine the headline onsen experience with some culture, four or five days lets you do Beppu and Yufuin and add either Nagayu for wellness or Kunisaki and the castle towns for depth. The prefecture is compact but the roads are winding, so a rental car pays off the moment you leave Beppu and Yufuin for the highlands, the peninsula or the coast. For help choosing a base, see our where to stay in Oita guide.

A couple of 2026 notes: the COMICO Art Museum needs an advance timed e-ticket; Kitsuki’s castle and combined tickets rose in price from April 2026 (use ¥400 and ¥1,500 figures); and Japan’s international departure tax rises from ¥1,000 to ¥3,000 per person from July 1, 2026, included in airfare. Plan around closing days for the smaller museums and temples, which are often irregular in rural Oita.

FAQ

What is Oita Prefecture best known for? Hot springs. Oita is Japan’s “Onsen Prefecture,” producing more hot-spring water than anywhere else in the country, and Beppu alone has thousands of vents. Its headline experiences are Beppu’s volcanic “hells” and varied baths, Yufuin’s refined onsen-and-art village, and Nagayu’s rare carbonated cure-springs, alongside the cliff Buddhas of the Kunisaki Peninsula.

What are the “hells” of Beppu? The jigoku are seven or eight vividly coloured volcanic hot-spring pools — a cobalt-blue lake, a blood-red pond, a steaming mud cauldron — that are too hot and strange to bathe in and are kept as viewing attractions. A combined two-day ticket (about ¥2,200 adult, approx. 2026) covers the set, most of them clustered in the Kannawa district.

Is Oita worth visiting beyond the hot springs? Yes. The Kunisaki Peninsula has one of Japan’s strangest sacred landscapes — giant Buddhas carved into cliffs, the head shrine of all Hachiman shrines, the oldest wooden hall in Kyushu — and the coastal old towns of Kitsuki and Usuki are beautifully preserved, the latter holding the country’s only National Treasure stone Buddhas. These suit a repeat visit.

What food should I eat in Oita? Toriten, the local chicken tempura, is the signature dish and is everywhere. Try Bungo beef, the seafood steamed over geothermal vents in Beppu, and the prized seki-aji and seki-saba mackerel from Saganoseki. In Usuki, fugu (pufferfish) is the winter speciality, often served alongside the town’s historic soy sauce and miso.

How many days do you need in Oita? Two days covers one area well. To combine the main onsen experience with some culture, plan four or five days — Beppu and Yufuin first, then either Nagayu for wellness or the Kunisaki Peninsula and the castle towns for depth. A rental car is worth it once you head beyond Beppu and Yufuin.
